    • createHunk

      public static IHunk createHunk(int start, String[] lines)
      Creates an IHunk instance.
      Parameters:
      start - the start position in the before file
      lines - content of the hunk. Each line starts with a control character. Their meaning is as follows:
      • '+': add the line
      • '-': delete the line
      • ' ': no change, context line
      Returns:
      IHunk instance

    • createFilePatch

      public static IFilePatch2 createFilePatch(IPath oldPath, long oldDate, IPath newPath, long newDate, IHunk[] hunks)
      Creates an IFilePatch2 instance and performs recalculation of all hunks' after positions. Hunk's after position is position in the file state after applying a patch. It is affected by all the hunks that are to be applied before a given one. This recalculation is necessary to keep IFilePatch2's state coherent.
      Parameters:
      oldPath - the path of the before state of the file
      oldDate - the timestamp of the before state of the file, see also IFilePatch2.DATE_UNKNOWN
      newPath - the path of the after state of the file
      newDate - the timestamp of the after state of the file, see also IFilePatch2.DATE_UNKNOWN
      hunks - a set of hunks to insert into IFilePatch2
      Returns:
      IFilePatch2 instance

    • addHunks

      public static IFilePatch2 addHunks(IFilePatch2 filePatch, IHunk[] toAdd)
      Adds IHunks to a given IFilePatch2 and performs recalculation of all hunks' after positions. Hunk's after position is position in the file state after applying a patch. It is affected by all the hunks that are to be applied before a given one. This recalculation is necessary to keep IFilePatch2's state coherent.
      Parameters:
      filePatch - a file patch to add hunks to
      toAdd - a set of IHunks to add
      Returns:
      newly created file patch with added hunks

    • removeHunks

      public static IFilePatch2 removeHunks(IFilePatch2 filePatch, IHunk[] toRemove)
      Removes IHunks from a given IFilePatch2 and performs recalculation of all hunks' after positions. Hunk's after position is position in the file state after applying a patch. It is affected by all the hunks that are to be applied before a given one. This recalculation is necessary to keep IFilePatch2's state coherent.
      Parameters:
      filePatch - a file patch to add hunks to
      toRemove - a set of IHunks to add
      Returns:
      newly created file patch with removed hunks
